+ * Document-method: setsockopt

+ *
+ * Sets a socket option. These are protocol and system specific, see your

+ *
+ * === Parameters
+ * * +level+ is an integer, usually one of the SOL_ constants such as
+ * Socket::SOL_SOCKET, or a protocol level.
+ * * +optname+ is an integer, usually one of the SO_ constants, such
+ * as Socket::SO_REUSEADDR.
+ * * +optval+ is the value of the option, it is passed to the underlying
+ * setsockopt() as a pointer to a certain number of bytes. How this is
+ * done depends on the type:
+ * - Fixnum: value is assigned to an int, and a pointer to the int is
+ * passed, with length of sizeof(int).
+ * - true or false: 1 or 0 (respectively) is assigned to an int, and the
+ * int is passed as for a Fixnum. Note that +false+ must be passed,
+ * not +nil+.
+ * - String: the string's data and length is passed to the socket.
+ *
+ * === Examples
+ *
+ * Some socket options are integers with boolean values, in this case
+ * #setsockopt could be called like this:
+ * sock.setsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR, true)
+ *
+ * Some socket options are integers with numeric values, in this case
+ * #setsockopt could be called like this:
+ * sock.setsockopt(Socket::IPPROTO_IP, Socket::IP_TTL, 255)
+ *
+ * Option values may be structs. Passing them can be complex as it involves
+ * examining your system headers to determine the correct definition. An
+ * example is an +ip_mreq+, which may be defined in your system headers as:
+ * struct ip_mreq {
+ * struct in_addr imr_multiaddr;
+ * struct in_addr imr_interface;
+ * };
+ *
+ * In this case #setsockopt could be called like this:

+ *
+ * sockaddr is specified as an array or a string.
+ * The array should be compatible to the value of IPSocket#addr or UNIXSocket#addr.
+ * The string should be struct sockaddr as generated by
+ * Socket.sockaddr_in or Socket.unpack_sockaddr_un.
+ *
+ * sockaddr examples:
+ * - ["AF_INET", 46102, "localhost.localdomain", "127.0.0.1"]
+ * - ["AF_INET6", 42304, "ip6-localhost", "::1"]

+ * In an AF_INET/AF_INET6 sockaddr array, the 4th element,
+ * numeric IP address, is used to construct socket address in the AddrInfo instance.
+ * The 3rd element, textual host name, is also recorded but only used for AddrInfo#inspect.
+ *
+ * family is specified as an integer to specify the protocol family such as Socket::PF_INET.
+ * It can be a symbol or a string which is the constant name
+ * with or without PF_ prefix such as :INET, :INET6, :UNIX, "PF_INET", etc.
+ * If ommitted, PF_UNSPEC is assumed.
+ *
+ * socktype is specified as an integer to specify the socket type such as Socket::SOCK_STREAM.
+ * It can be a symbol or a string which is the constant name
+ * with or without SOCK_ prefix such as :STREAM, :DGRAM, :RAW, "SOCK_STREAM", etc.
+ * If ommitted, 0 is assumed.
+ *
+ * protocol is specified as an integer to specify the protocol such as Socket::IPPROTO_TCP.
+ * It must be an integer, unlike family and socktype.
+ * If ommitted, 0 is assumed.

- *
- * returns a new instance of AddrInfo.

- * sockaddr means struct sockaddr which can be used for connect(2), etc.
- * family, socktype and protocol are integers which is used for arguments of socket(2).
- *
- * sockaddr is specified as an array or a string.
- * The array should be compatible to the value of IPSocket#addr or UNIXSocket#addr.
- * The string should be struct sockaddr as generated by
- * Socket.sockaddr_in or Socket.unpack_sockaddr_un.
- *
- * sockaddr examples:
- * - ["AF_INET", 46102, "localhost.localdomain", "127.0.0.1"]
- * - ["AF_INET6", 42304, "ip6-localhost", "::1"]

- *
- * In an AF_INET/AF_INET6 sockaddr array, the 4th element,
- * numeric IP address, is used to construct socket address in the AddrInfo instance.
- * The 3rd element, textual host name, is also recorded but only used for AddrInfo#inspect.
- *
- * family is specified as an integer to specify the protocol family such as Socket::PF_INET.
- * It can be a symbol or a string which is the constant name
- * with or without PF_ prefix such as :INET, :INET6, :UNIX, "PF_INET", etc.
- * If ommitted, PF_UNSPEC is assumed.
- *
- * socktype is specified as an integer to specify the socket type such as Socket::SOCK_STREAM.
- * It can be a symbol or a string which is the constant name
- * with or without SOCK_ prefix such as :STREAM, :DGRAM, :RAW, "SOCK_STREAM", etc.
- * If ommitted, 0 is assumed.
- *
- * protocol is specified as an integer to specify the protocol such as Socket::IPPROTO_TCP.
- * It must be an integer, unlike family and socktype.
- * If ommitted, 0 is assumed.
- * Note that 0 is reasonable value for most protocols, except raw socket.

- * Document-method: setsockopt
- * call-seq: setsockopt(level, optname, optval)
- *
- * Sets a socket option. These are protocol and system specific, see your
- * local sytem documentation for details.
- *
- * === Parameters
- * * +level+ is an integer, usually one of the SOL_ constants such as
- * Socket::SOL_SOCKET, or a protocol level.
- * * +optname+ is an integer, usually one of the SO_ constants, such
- * as Socket::SO_REUSEADDR.
- * * +optval+ is the value of the option, it is passed to the underlying
- * setsockopt() as a pointer to a certain number of bytes. How this is
- * done depends on the type:
- * - Fixnum: value is assigned to an int, and a pointer to the int is
- * passed, with length of sizeof(int).
- * - true or false: 1 or 0 (respectively) is assigned to an int, and the
- * int is passed as for a Fixnum. Note that +false+ must be passed,
- * not +nil+.
- * - String: the string's data and length is passed to the socket.
- *
- * === Examples
- *
- * Some socket options are integers with boolean values, in this case
- * #setsockopt could be called like this:
- * sock.setsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR, true)
- *
- * Some socket options are integers with numeric values, in this case
- * #setsockopt could be called like this:
- * sock.setsockopt(Socket::IPPROTO_IP, Socket::IP_TTL, 255)
- *
- * Option values may be structs. Passing them can be complex as it involves
- * examining your system headers to determine the correct definition. An
- * example is an +ip_mreq+, which may be defined in your system headers as:
- * struct ip_mreq {
- * struct in_addr imr_multiaddr;
- * struct in_addr imr_interface;
- * };
- *
- * In this case #setsockopt could be called like this:
- * optval = IPAddr.new("224.0.0.251") + Socket::INADDR_ANY
- * sock.setsockopt(Socket::IPPROTO_IP, Socket::IP_ADD_MEMBERSHIP, optval)

- * Document-method: getsockopt
- * call-seq: getsockopt(level, optname)
- *
- * Gets a socket option. These are protocol and system specific, see your
- * local sytem documentation for details. The option is returned as
- * a String with the data being the binary value of the socket option.
- *
- * === Parameters
- * * +level+ is an integer, usually one of the SOL_ constants such as
- * Socket::SOL_SOCKET, or a protocol level.
- * * +optname+ is an integer, usually one of the SO_ constants, such
- * as Socket::SO_REUSEADDR.
- *
- * === Examples
- *
- * Some socket options are integers with boolean values, in this case
- * #getsockopt could be called like this:
- * optval = sock.getsockopt(Socket::SOL_SOCKET,Socket::SO_REUSEADDR)
- * optval = optval.unpack "i"
- * reuseaddr = optval[0] == 0 ? false : true
- *
- * Some socket options are integers with numeric values, in this case
- * #getsockopt could be called like this:
- * optval = sock.getsockopt(Socket::IPPROTO_IP, Socket::IP_TTL)
- * ipttl = optval.unpack("i")[0]
- *
- * Option values may be structs. Decoding them can be complex as it involves
- * examining your system headers to determine the correct definition. An
- * example is a +struct linger+, which may be defined in your system headers
- * as:
- * struct linger {
- * int l_onoff;
- * int l_linger;
- * };
- *
- * In this case #getsockopt could be called like this:
- * optval = sock.getsockopt(Socket::SOL_SOCKET, Socket::SO_LINGER)
- * onoff, linger = optval.unpack "ii"
